He also said that taxi drivers have seen a 20 to 40 percent drop in their income this month.

And WWD profiled a retailer who was disappointed by Olympic traffic:

The New West End Company — which represents businesses on Oxford, Bond and Regent streets — estimated earlier this year that retailers in London’s West End would make 16.6 million pounds, or $26 million at current exchange, in additional revenue as a direct result of the Olympics.

But earlier this week, they were forced to take action to drive shoppers back into the town center.

“We have been working on measures to reverse the significant drop in retail spending and visitors into the West End,” the company said in a statement that was sent to its member retailers, and which was seen by WWD. “The forecasts for this summer predicted a different trading pattern and the lack of London workers and domestic visitors has been quickly apparent as a result of Transport for London traffic demand management.”

So far, the Olympics haven't been the stimulus that Londoners had hoped for.
